In an era where the complexity and cost of Failure Analysis tools and techniques is rapidly expanding, it is easy sometimes to lose sight of the basic tool and technique required for successful root-cause analysis. That technique is intellectual curiosity and the tool is the human brain. This paper will describe a simple methodology to insure that this tool and technique are properly engaged either concomitant with or in the absence of state-of-the-art instrumentation and computation. Two simple case studies will be used to illustrate where the Failure Analysis process can easily go awry without proper attention to detail, and, conversely, from too much attention to detail.
